I originally deleted Firefox by accident and have downloaded it via Microsoft Store. All seems well then after I click on the app to open it, I Get the ‘Windows cannot find C:\Program Files\Mozilla Firefox\firefox.exe. Make sure you typed the name correctly, and try again’ for ‘Firefox’ error how can this be corrected?

I was attempting to print a document I created through a 3rd party site, but on the Firefox browser. Unfortunately, when I attempt to print, the document includes the website I'm using, along with other information that is not related to the document. How can I prevent Firefox from including that text when I print? I was unable to locate the correct setting. Thank you.

Firefox version 115.23.0esr (64-bit) on macOS Version 10.13.6 on Mac mini (Mid 2010), Processor- 2.4 GHz Intel Core 2 Duo Memory- 8 GB 1067 MHz DDR3 Graphics- NVIDIA GeForce 320M 256 MB Works ok on my iPhone 16. Computer getting too old? Doesn't work now on my MacBook of the same vintage either.

Firefox will not play video from a website. If I save the video, it is a MP4 file. Windows Media Player and VLC will play the video file. But the browser shows the message: "No video with supported format and MIME type found."

Chrome and Edge will play this video correctly in their browsers. Firefox will not play the video on 3 different computers, and even when a different user account is involved (without Firefox sync).

The evidence seems to point at firefox. The website is a Wordpress site.

Is it possible that the website is the problem? If so, why do Edge and Chrome work?

I uninstalled Firefox (latest version) and reinstalled it. Not fixed.

My windows updates are current, as are Dell updates.

This is stumping me. I hope someone can help.

Hello. For a while now I have been using the picture-in-picture feature to play a video in the corner while using other applications. It has been a great help as I have a single monitor.

Unfortunately, I have recently been encountering a severe issue with the feature over the last week. When attempting to use picture-in-picture while my computer is running a videogame (through Steam) my entire system will freeze. The audio still plays as normal, but the image is frozen and the system is unresponsive until I force a shutdown and reboot.

Any help at all in with this issue would be greatly appreciated, thank you.
